Patent DE-3120767-A1 (DE)
Title: Microprocessor
Inventor: MOR YESHAYAHU
IPC: G06F21/71
Filed: 1981-05-25
Abstract: A high-performance microprocessor system has a central processing unit which exhibits an independent address data path and an independent arithmetic logic unit (ALU) data path. Each of these is suitable for simultaneous processing during one clock period. The data paths are connected to a common input multiplexer in order to receive information from an information bus. A common bus register receives information from the input multiplexer and the common output multiplexer is connected in such a manner that it receives information from the bus register and other units in the data paths in order to supply the information to the information bus. The arithmetic logic unit data path exhibits a set of registers which contains at least one bidirectional shift register which is logically combined with another register in the set of registers. An internal counter forms a part of the arithmetic logic unit data path and supplies information both to the set of registers and to the arithmetic logic unit. The bus register is divided into at least two one-byte registers in order to allow a fast execution of byte commands. A control unit for the microprocessor system includes a programmable logic array (PLA) which exhibits at least one program for testing the microprocessor system function, together with a control line which is connected to a console of a system which includes the microprocessor system in order to enable the user to initiate system checks from the console. Data and programs in the microprocessing system are protected against access or modification by unauthorised users by means of a special function (abort function). The design of the arithmetic logic unit data path allows very fast floating-point arithmetic operations to be executed. It also permits much faster division operations than conventional microprocessors. The microprocessor system is advantageously accommodated in a single IC chip in TTL and IIL bipolar technology.
Patent DE-3124042-A1 (DE)
Title: Dynamometer
Inventor: HITCHCOCK KEITH NORMAN
IPC: G01L3/20
Filed: 1981-06-19
Abstract: The dynamometer according to the invention, for testing internal combustion engines, has an input clutch (112) which can be rotated about an axis (126). The dynamometer is connected by this axis to the engine to be investigated. A hydraulic pump (109) is driven by the input clutch and is connected to a distributor (114), which is connected via a load cell (132) to the dynamometer frame (101). A fixed distributor (125) is fixed on a frame (101) and is connected via pipes (122, 123, 124) to the pump distributor (114). At the axis (126) of the input clutch, the pipes are connected in articulated fashion to the pump distributor (114), the said clutch axis intersecting the respective pipe axes. The forces resulting from the pressure of the fluid in the pipes and in the pump distributor thus act via the axis (126) of the input clutch and do not exert any torque about this axis. Accordingly, the forces resulting from the pressure of the fluid do not impair the measurements by the load cell (132) of the loads applied by the engine to be investigated, with the result that the accuracy of the dynamometer is considerably improved.   <IMAGE>

Patent DE-3128046-A1 (DE)
Title: Conveying and lift system for surmounting planes at different levels
IPC: B66B9/08
Filed: 1981-07-16
Abstract: To surmount planes at different levels in buildings or flats, lift and/or conveying equipment has hitherto been presented for handicapped persons which, from its construction and design, gives the impression of robust hoists or lifts which are very similar to those in trade and industry, because they are in a fixed position and take up permanent space and therefore get in the way. Subsequent installation of such systems, in particular in the private housing sector, is as a rule also associated with complicated and costly constructional measures, whereas in the conveying and lift system proposed according to the invention, for example as a "track", prepared staircase parts already present to a very large extent, such as handrails, balustrades or running rails mounted on the wall, can be used for the operation; and because the "trolley" designed as drive supporting group consists of members which can be assembled individually, it can be assembled, for example in any length (modular construction principle), depending on the project case. Special load-suspension means for the particular requirement, such as seats, standing frames, handles, supporting frames for wheelchairs etc., are suspended/locked in place on the "trolley". The load-suspension means are uncoupled from the "trolley" and the latter itself is removed from its "track" and everything together can be put into safekeeping.

Title: Device for monitoring the slip on wheels of motor vehicles
Inventor: WERNER GUENTHER
IPC: B60T8/68
Filed: 1982-02-25
Abstract: The device is intended to give the vehicle driver an alarm signal when the slip state of individual wheels of the motor vehicle becomes critical, but is not intended to signal non-critical slip states. For this purpose each wheel is provided with a sensor unit which emits one sensor pulse per wheel revolution. A counter provided for each wheel and counting count pulses between two sensor pulses is controlled by the sensor pulses by means of a start/stop device. By means of a computing circuit for each wheel a wheel speed signal is formed from each count value. A wheel acceleration signal is produced from two successive count values. The computing circuit is set up to compare the acceleration signal from each wheel with a predetermined deceleration threshold. In addition the computing circuit is also set up to compare the acceleration signals of all wheels with one another and also to compare the greatest difference between two acceleration signals thus calculated with a predetermined deceleration difference threshold. In addition the computing circuit is set up to compare the speed signals of all wheels with one another and designed to further compare the greatest difference between two speed signals thus calculated with a speed difference threshold predetermined as a function of the vehicle speed. An alarm device, which emits an alarm if one of the said thresholds is exceeded, is connected to the computing circuit. <IMAGE>

Title: Melt temperature probe for viscous, laminar-flow media
Inventor: BINNENKADE TOM
IPC: G01K13/02
Filed: 1982-04-05
Abstract: The invention relates to a temperature probe for viscous, laminar-flow media, in particular for application in plastics extruders. Its aim is to measure the melt temperature in specific parts of the processing machines, the measured values being used for process monitoring, process optimisation and quality control. It is the object of the invention to provide a melt temperature probe which has a robust design unconditionally required for the above-named field and is thus reliable in operation and, on the other hand, enables exact measurement of individual isotherms in the flow channel. The object is achieved according to the invention when the measuring element is held by a plate-shaped measuring element support which is arranged parallel to the flow direction. A small adjustment angle relative to the flow direction is intended to prevent the formation of dead water. This plate is therefore always located on an isotherm in the flow channel. Heat dissipation defects perpendicular to the flow direction are prevented because the plate is contacted on one side by a thermal insulating body. This insulating body simultaneously provides a mechanical support for the plate, whose diameter/thickness ratio is intended to be as large as possible.
